Abstract

La presente invencion proporciona un metodo y aparato (1) para tratar una corriente de alimentacion (2) para un dispositivo de flotacion (3) comprendiendo un agitador mecanico (30, 50) en un tanque (7), comprendiendo la corriente de alimentacion (2) particulas solidas (1 0). El metodo comprende generar microburbujas (8) en una corriente de agua de dilucion (9), mezclar la corriente de agua de dilucion con la corriente de alimentacion para facilitar la union de las microburbujas con las particulas solidas en la corriente de alimentacion y generar burbujas (22) para la union con particulas solidas unidas a microburbujas, y conectar de manera fluida la corriente de alimentacion con el dispositivo de flotacion. El aparato comprende un conducto de corriente de alimentacion (4) conectado de manera fluida con el dispositivo de flotacion, un conducto de corriente de agua de dilucion (5) conectado de manera fluida con el conducto de corriente de alimentacion para transportar la corriente de agua de dilucion con la corriente de alimentacion, y un generador de microburbujas (6) conectado con el conducto de corriente de agua de dilucion para generar microburbujas en la corriente de agua de dilucion.The present invention provides a method and apparatus (1) for treating a feed stream (2) for a flotation device (3) comprising a mechanical stirrer (30, 50) in a tank (7), the feed stream comprising ( 2) solid particles (1 0). The method comprises generating microbubbles (8) in a dilution water stream (9), mixing the dilution water stream with the feed stream to facilitate the binding of the microbubbles with the solid particles in the feed stream and generating bubbles (22) for binding with solid particles bound to microbubbles, and fluidly connecting the feed stream with the float device. The apparatus comprises a feed stream conduit (4) fluidly connected to the buoyancy device, a dilution water stream conduit (5) fluidly connected to the feed stream conduit to transport the water stream of dilution with the feed stream, and a microbubble generator (6) connected with the dilution water stream conduit to generate microbubbles in the dilution water stream.
